Thanks to a broadcast email from the Civil War Preservation Trust, which contained a nice story on Civil War blogs, including an excellent article by Eric Wittenberg [Rantings], found here -- Trust -- I learned y'day of another Michigan Civil War-related blog. It's called "Daughter of the 24th Michigan" and is located here: Daughter of 24th.
The author is a descendant of a 16-year old member of that Michigan regiment in the Iron Brigade. A bio of his story, including the fact that he was one of the many casualties in the Brigade on the first day at Gettysburg, is on her site.
Her website certainly bears visiting on a regular basis, and I've added it to my links.
